Choose whether the outcomes are impossible, unlikely, even chance, likely, or certain:
When a coin is tossed, heads will come up.
Finding the outcome of an event
If an event is never going to happen then you can describe the probability as impossible
If an event has a small chance of happening then you can use the word unlikely to describe the probability
If an event has a fifty-fifty chance of happening then you can use the word even chance to describe the probability
If an event has a good chance of happening then you can use the word likely to describe the probability.
If an event is definitely going to happen then the probability will be described as certain to happen.
Now, when a coin is tossed up, there is fifty percent chance that heads will come and fifty percent chance tails will come.
Hence, the outcome of the given event is even chance.
